Patent GB-571693-A (GB)
Title: An improved manufacture of magnesia-containing refractories
IPC: C04B35/03
Filed: 1943-07-14
Abstract: Refractories containing magnesia and a magnesium silicate have 1-10 per cent of calcium fluoride added to them in order to react with any low-melting silicate such as monticellite and transform it to a silicate of higher melting point.  On firing, the fluoride flows readily throughout the mass of the refractory and is finally decomposed.  The refractory contains at least 70 per cent magnesia, and may also contain chromite.  The amount of fluoride required is obtained by subtracting the molecular equivalent of lime in the refractory from twice the molecular equivalent of silica and multiplying the result by 78.

Title: Improvements relating to hot-gas reciprocating engines and refrigerating engines operating on the reversed hot-gas reciprocating engine cycle
IPC: F02G1/055
Filed: 1948-04-26
Abstract: 665,989. Hot gas engines. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. April 26, 1948 [April 29, 1947], No. 11454/48. Class 7(i) [Also in Group XIII] A cylinder head for a hot gas engine has a generally cylindrical portion of which the wall presents a corrugated form so as to provide a plurality of recesses the thickness of the portions of the wall defining the recesses being less than three millimetres and the head being manu-. factured by a precision method of casting. The use of a precision method of casting enables the spaces for the passage of the working medium to be formed very accurately. The figures show a cylinder head of a hot gas engine in which a partition 2 forms spaces 5 for a heating medium and spaces 9 for the working medium. Projections.11 and 13 are provided on the walls of the partition for the purpose of increasing the surface area thereof and partitions 12 secured for example by welding are provided for strengthening purposes. The inner and/or outer projections may be integral with the cylinder head. They may also be very thin and formed in large numbers. It is stated that the thickness of the portions of the wall defining the recesses may be less than that required to withstand the forces which arise due to the pressure of the working medium. A strengthening ring may surround a cylindrical portion of the head.

Title: Pulsed droplet ejecting system
IPC: H04N1/40
Filed: 1974-03-14
Abstract: 1432321 Copying by scanning GOULD Inc 14 March 1974 [14 March 1973] 11493/74 Heading H4F Ink ejection apparatus for use, for example, in a facsimile receiver, includes ink ejection means which fails to eject ink in response to a drive pulse having an amplitude less than a threshold level and ejects ink in a predictable manner in response to a drive pulse having an amplitude above a higher second level, drive pulses with amplitudes falling within a threshold range extending from the threshold level to the second level not being applied to the ink ejection means; this eliminates errors caused by drive pulses with amplitudes falling within the threshold range which would produce ink drops of low velocities and unstable trajectories. Drive pulses with amplitudes below the threshold level may also not be applied to the ink ejection means. In the embodiment of Fig. 5 image signals control a modulator 37 to derive the drive pulses, drive pulses of amplitudes less than the second level being blocked by a gate 59 in response to the output of a differential amplifier 55 receiving, via contact 65 of switch 62, the image signals from potentiometer 38 or amplifier 41. In an alternative embodiment gate 59 is omitted, the bias supply for potentiometer 40 being obtained, via an inverter, from the output of amplifier 55; alternatively the inverting input of amplifier 41 may receive the image signals. The ink ejection means comprises a nozzle (1, Fig. 1, not shown) connected via a conduit (4) to an ink reservoir (7), the drive pulses being applied to a piezoelectric transducer (10) which surrounds part of the conduit and applies pressure pulses to the ink in the conduit.

Shaft 30 carries rigidly a lever 47 and freely a lever 51 integral with a plate 54 urged into engagement with a projection 56 from lever 47 by torsion spring 58. Lever 51 is connected by link 52 to the engine governor. The setting of the latter can be temporarily reduced without altering the setting of lever 12 by depressing pedals 63 on a further lever 62 thus causing abutment 64 to move plate 54 and lever 51 away from projection 56 on lever 47 against the action of spring 58.

Title: Brick stopping and grouping apparatus

Abstract: 1333525 Spacing, batching and stopping bricks on an endless conveyer FORREST PASCHAL MACHINERY CO 15 March 1972 [22 March 1971] 11960/72 Heading B8A Bricks 10 on a conveyer belt 12 are advanced until the leading brick engages an abutment 24 carried by a plunger 50 which is rigid with an air cylinder 26. The latter is also rigid with a member 52 slidably mounted in a frame 42. The piston (shown in broken lines in Fig. 2) of cylinder 26, is rigid with a plunger 56 which is connected to the piston of a cylinder 28. The latter is slidable relative to the frame 42, but normally bears on a manually-adjustable stop 30. At this stage of the working cycle, a pressure source 58 (Fig. 2) is connected by a two-way solenoid valve 60 to lines 62, 64, leading to the cylinders 26, 28. Since the line 62 passes through a pressure-reducing valve 66, the pressure in the cylinder 26 is lower than that in the cylinder 28. Thus the abutment 24, under the pressure of the conveyed column of bricks, advances the cylinder 26 to a first displaced position (Fig. 3, not shown). A switch 72 is thereby closed. This energizes a solenoid valve (90) (Fig. 5, not shown) which applies pressure to grippers 16, 18. The action of the latter halts the bricks upstream of the grippers. The solenoid valve 60 is also energized by the action of the switch 72, and this reverses the pressure between the ends of the cylinder 28 and causes the plunger 56 to drag the cylinder 26 to a second displaced position (Fig. 4, not shown). A switch 74 is thereby closed and this energizes a solenoid valve 96. The latter pressurizes a motor (not shown) which drives chains 23, 23. These carry conveyer flights 20, 20, which deflect the column of bricks on to a table or conveyer 22. By the actuation of a manually-operated switch (92) (Fig. 5, not shown), a plunger 35 is pressurized. This displaces the whole frame 42 laterally clear of the conveyer belt 12 so that, for example, a defective run of bricks may be discharged at the end of the conveyer.
